Sub-Doppler Double-Resonance Spectroscopy of Methane Using a Frequency Comb Probe
Aleksandra Foltynowicz, Lucile Rutkowski, Isak Silander +7
We report the measurement of sub-Doppler double-resonance transitions in methane using a 3.3 m continuous wave optical parametric oscillator to pump transitions in the fundament…
Broadband calibration-free cavity-enhanced complex refractive index spectroscopy using a frequency comb
Alexandra C. Johansson, Lucile Rutkowski, Anna Filipsson +4
We present broadband cavity-enhanced complex refractive index spectroscopy (CE-CRIS), a technique for calibration-free determination of the complex refractive index of entire molec…
Optical frequency comb Faraday rotation spectroscopy
Alexandra C. Johansson, Jonas Westberg, Gerard Wysocki +1
We demonstrate optical frequency comb Faraday rotation spectroscopy (OFC-FRS) for broadband interference-free detection of paramagnetic species. The system is based on a femtosecon…
An experimental water line list at 1950 K in the 6250 -- 6670 \cm\ region
Lucile Rutkowski, Aleksandra Foltynowicz, Florian M. Schmidt +7
An absorption spectrum of HO at 1950 K is recorded in a premixed methane/air flat flame using a cavity-enhanced optical frequency comb-based Fourier transform spectromet…
Sensitive and broadband measurement of dispersion in a cavity using a Fourier transform spectrometer with kHz resolution
Lucile Rutkowski, Alexandra C. Johansson, Gang Zhao +4
Optical cavities provide high sensitivity to dispersion since their resonance frequencies depend on the index of refraction. We present a direct, broadband, and accurate measuremen…
Optical Frequency Comb Fourier Transform Spectroscopy with Sub-Nominal Resolution - Principles and Implementation
Lucile Rutkowski, Piotr Maslowski, Alexandra C. Johansson +2
Broadband precision spectroscopy is indispensable for providing high fidelity molecular parameters for spectroscopic databases. We have recently shown that mechanical Fourier trans…
